AOKII Fitness Tracker


Fitness tracking bracelets and smart watches are helpful tools for athletes, cyclists, weight lifters, and the Average Joe or Jane. Fitness trackers can monitor your heart rate to give more accurate calorie expenditure estimates than online exercise sites, and can tell you things you didn’t know about yourself. If you want to sleep better and be more active--even if you aren’t a pro athlete--a fitness tracker is a great way to monitor your progress and keep the data easily stored for historical tracking within your smartphone.

We’re willing to bet you’ve heard about Fitbit, one of the best-selling brands of fitness trackers. The Fitbit Charge series has been their number-one selling tracker, but they don’t come cheap. We wanted to find a fitness tracker of comparable quality and with similar features, but at a low price. So our research team spent a lot of time wearing different trackers and downloading different apps to sync up our data. Vibrating alarms were a little terrifying at first, while the sedentary notifications were unwelcome reminders! But we got through it, and have an alternative to the Fitbit Charge 2: the AOKII Waterproof Fitness Tracker, a neat little high-tech bracelet with a pleasingly low price. If you’re torn between what tracker to get, take a look at our comparisons below to get a better idea of what these two products can offer you.

Who Should Buy The Brand

The Fitbit Charge 2 Fitness Tracker may be one of the best fitness tracker models for weight lifting, but we wouldn’t call it an affordable fitness tracker. It offers some fun features, like guided breathing sessions and reminders to move if you’ve been sitting for a while. It can be set to track different sports and exercises (including weight lifting) to give you a more accurate idea of your stats. It syncs wirelessly to the Fitbit app, which is available for a range of Apple, Android, and Windows phones. It also offers lots of color options and three sizes to suit a range of tastes and wrists from 5.5 inches around (with the small band) to 9.3 inches (with the XL band). However, if you’re not sure you want to invest so much upfront in a fitness tracker (especially if it’s your first one), we recommend taking a look at the AOKII Fitness Tracker. Besides being available at a low price, this AOKII tracker is also waterproof, while the Charge 2 is only water resistant. 

Who Should Buy The Alternative

The AOKII Fitness Tracker is our pick for the best cheap fitness tracker. Like the Charge 2, it tracks your steps, distance, calories, heart rate, and sleep. All of this data uploads to the Happysport app, which is available for Apple and Android devices. Like the Fitbit app, you can set fitness goals and targets, and see your data arranged neatly for your enjoyment. This tracker’s IP67 waterproof rating means it can be in up to one meter of water for thirty minutes, so you can take it in the shower or in the pool without worrying. This affordable fitness tracker offers a similar design to the Charge 2, with a black band that can fit wrists from 4.8 to 6.75 inches around. It also has similar battery life, a vibrating alarm feature, and can be used to alert you of different phone notifications as well as when you need to take a few more steps. If you’re looking for an inexpensive fitness tracker, this tracker from AOKII is a great option to consider.

Step counter tracker


The Fitbit Charge 2 tracks the steps you take and even the number of floors you climb each day. Even if you aren’t really “into” fitness, setting a goal to walk more can improve your health and even help you lose weight. A fitness tracker is more versatile than a plain pedometer, and looks better too.

step counter tracker


The AOKII fitness tracker also acts as a pedometer to help you reach your daily step count goals. Whether you want to try to increase your steps to 5,000 per day (the average sedentary person takes 1,000 to 3,000 steps per day), or take it to the next level with 10,000 steps, the tracker can help.

Distance tracker


The Fitbit Charge 2 monitors your total distance traveled using GPS, which is especially helpful for runners and cyclists. Combined with the step counting feature, you can get a better idea of how far you’re really traveling each day.

Distance tracking


The AOKII fitness tracker also keeps track of your total distance traveled. If you ever feel like you spend most of your time in the same place (i.e. at work and at home), seeing how much you actually move around might help your outlook!

heart rate monitor

Heart Rate

The Fitbit Charge 2 uses a method called PurePulse to continuously monitor your heart rate all day. Calorie counts for exercise are more accurate when based off of heart rate, because the actual “strain” you’re putting your body under can be taken into account more fully.

Heart Rate

The AOKII fitness tracker also tracks your heart rate. You can switch this function off through the app if you want to conserve battery or keep the bracelet from monitoring the way your heart beats faster in front of your crush or while giving a presentation to a crowd!

calorie tracker


The Fitbit Charge 2 tracks your calories burned based on your heart rate. Whether you want to gain, lose, or maintain your weight, having an estimate of your calorie output can help you make healthier choices to meet your goals.

calorie monitoring


The AOKII fitness tracker also tracks your calories burned using its heart rate monitor function. Remember that sometimes these trackers can mistakingly think you are exercising when you have a quicker pulse due to unexpected stress or a surprise--but it doesn’t count!

sleep tracker


The Fitbit Charge 2 tracks your sleep, both the length and quality of it, and can wake you with a vibrating alarm. Do you wake up feeling tired and out of sorts? If you want to make changes to improve your sleep, an activity tracker makes it easier to find out if the changes are having an impact.

sleep monitor


The AOKII waterproof activity tracker also monitors your sleep length and sleep patterns. You can see this data spread out in the app and figure out what makes you sleep better or worse. Making healthy lifestyle changes is a lot easier when you can have consistent data to back you up!

water resistant


The Fitbit Charge 2 is water resistant but not waterproof. This means it can withstand rain, sweat, and splashes, but shouldn’t be taken into the shower or worn in the water. The Fitbit Flex 2 is a waterproof alternative if you prefer the Fitbit brand.



The AOKII activity tracker is waterproof, and has been given an IP67 rating. This rating means it has been tested by being submerged in one meter of water for up to thirty minutes, and will be waterproof in these conditions.

battery life

Battery Life

The Fitbit Charge 2 lasts up to five days on a single charge, so you won’t have to take it off very often to recharge. It takes about one or two hours for the Lithium Polymer battery to reach a full charge again.

Battery Life

The AOKII fitness tracker also lasts about five days on one charge. The 60mAH Lithium Polymer battery, like the Fitbit Charge 2, can reach a full charge in one to two hours when plugged into the charger.



The Fitbit Charge 2 has an OLED screen that measures 1.2 inches diagonally. OLED displays are easy to see even in direct sunlight.

screen size


The AOKII fitness tracker also has an OLED screen, although it measures 0.87 inches diagonally, so it is a bit smaller than the Fitbit’s.

phone notifications

Phone Notifications

The Fitbit Charge 2 can alert you to calls, texts, and calendar events. Using Bluetooth 4.0, the Charge 2 can display notifications from your smartphone or vibrate to alert you.

app notifications

Phone Notifications

The AOKII fitness tracker can also notify you about incoming calls and text messages with Bluetooth 4.0, which can be handy for when you walk away from your phone.

color options

Colors & Sizes

The Fitbit Charge 2 comes in small and large sizes, and four colors: black, blue, plum, and teal. Small bands fit wrists 5.5-6.5 inches around, while the large bands fit wrists 6.5-7.7 inches around. XL bands fit up to 9.3-inch wrists! This makes the Charge 2 a better option for larger wrist sizes. (https://www.fitbit.com/content/assets/charge/charge_sizing_guide.pdf)

size options

Colors & Sizes

The AOKII fitness tracker comes in one size, which can fit wrists from 4.8 inches to 6.75 inches around, and bands are currently only available in black. The AOKII can fit smaller wrists more comfortably than the Charge 2, but the one-size design is also compatible with most average wrist sizes.
